We note that the Ilvermorny School of Witchcraft and Wizardry in North America is mentioned in the recent film Fantastic Beasts and Where to Find Them. For reasons outlined here, this film is not canon for the Muggles' Guide, and so this school will not be included here.

Intermediate warning: Details follow which you may not wish to read at your current level.

There are a few characters who are not what they seem, but who and what they actually are is a significant part of the story and should not be revealed, as it is something of a spoiler in some cases. A classic example of this is Alastor "Mad-Eye" Moody, who teaches Defence Against the Dark Arts in Harry's fourth year. A key point in the story is that Moody is, in fact, not Moody, but is Barty Crouch Jr., a Dark wizard, Death Eater, and escapee from Azkaban. Partly to avoid the spoiler, we list Harry's fourth year teacher as Moody; but we also note that Barty is at great pains, probably literal in the morning as he recasts himself in Moody's image once the Polyjuice Potion has worn off, to act like Alastor Moody. With very few exceptions, the class is taught as Moody would have taught it, which would also partially justify listing Moody rather than Barty as the Defence Against the Dark Arts teacher.
